Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. An analyte monitoring system, comprising: an analyte sensor configured to perform measurements indicative of analyte levels; a sensor electronics unit communicatively coupled to the analyte sensor, the sensor electronics unit configured to: receive the measurements indicative of analyte levels from the sensor; operate in a first power mode and a second power mode; transmit sensor information when in the first power mode over a first communication protocol using a Bluetooth module, and receive and respond to one or more commands in the second power mode over a second communication protocol using a Near Field Communication (NFC) module; and a display device configured to: transmit the one or more commands to the sensor electronics unit in the second power mode using the second communication protocol; receive communication parameters comprising information associated with one or more encryption/decryption keys, the communication parameters being transmitted and received in the second power mode using the second communication protocol; and use the received communication parameters to decrypt sensor information sent to the display device over the first communication protocol by the sensor electronics unit after the first communication protocol is established by Bluetooth pairing of the display device with the sensor electronics.
An analyte monitoring system includes an analyte sensor that measures analyte levels and a sensor electronics unit connected to the sensor. The sensor electronics unit operates in two power modes: a first mode for transmitting sensor data via Bluetooth and a second mode for receiving and responding to commands via Near Field Communication (NFC). In the first mode, the unit sends analyte data using a Bluetooth module. In the second mode, it communicates with a display device using NFC, receiving commands and transmitting communication parameters, including encryption/decryption keys. The display device sends commands to the sensor electronics unit in the second mode and receives the communication parameters over NFC. After Bluetooth pairing is established, the display device uses the received keys to decrypt sensor data transmitted over Bluetooth. This system enables secure, low-power communication between the sensor and display, ensuring data integrity while minimizing power consumption. The NFC mode allows for initial setup and key exchange, while Bluetooth handles continuous data transmission.
2. The analyte monitoring system of claim 1 , wherein the communication parameters comprise pairing information used to establish the first communication protocol by Bluetooth pairing.
The analyte monitoring system is designed for continuous or periodic measurement of analytes such as glucose in biological samples, such as blood or interstitial fluid. The system includes a sensor module that detects analyte levels and a communication module that transmits data to an external device, such as a smartphone or medical monitor. A key challenge in such systems is ensuring reliable and secure data transmission between the sensor and the external device, particularly in environments with multiple wireless devices. The system addresses this by incorporating communication parameters that include pairing information used to establish a Bluetooth pairing protocol. This pairing process ensures a secure and stable connection between the sensor module and the external device, reducing interference and unauthorized access. The pairing information may include encryption keys, device identifiers, or authentication credentials that facilitate a trusted communication link. By using Bluetooth pairing, the system ensures compatibility with widely available devices while maintaining data integrity and security. This approach is particularly useful in medical applications where accurate and reliable data transmission is critical for patient monitoring and treatment decisions. The system may also include additional features such as data encryption, error correction, and power management to further enhance performance.
